[dpdk-dev] [PATCH 1/2] app/eventdev: fix order test port creation

[<pbhagavatula@marvell.com>]

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Configure event ports based on the underlying event device info rather
than using hardcoded values.

Cc: stable@dpdk.org
Fixes: 5710e751813e ("app/testeventdev: add order port setup")
